35 bool "Direct Access (DAX) support"
37 depends on !(ARM || MIPS || SPARC)
39 Direct Access (DAX) can be used on memory-backed block devices.
40 If the block device supports DAX and the filesystem supports DAX,
41 then you can avoid using the pagecache to buffer I/Os. Turning
42 on this option will compile in support for DAX; you will need to
43 mount the filesystem using the -o dax option.
45 If you do not have a block device that is capable of using this,
46 or if unsure, say N. Saying Y will increase the size of the kernel

72 This option enables standard file locking support, required
73 for filesystems like NFS and for the flock() system

116 bool "Tmpfs virtual memory file system support (former shm fs)"
119 Tmpfs is a file system which keeps all files in virtual memory.
121 Everything in tmpfs is temporary in the sense that no files will be
122 created on your hard drive. The files live in memory and swap
123 space. If you unmount a tmpfs instance, everything stored therein is

129 bool "Tmpfs POSIX Access Control Lists"
134 POSIX Access Control Lists (ACLs) support additional access rights
135 for users and groups beyond the standard owner/group/world scheme,
136 and this option selects support for ACLs specifically for tmpfs
139 If you've selected TMPFS, it's possible that you'll also need
140 this option as there are a number of Linux distros that require
141 POSIX ACL support under /dev for certain features to work properly.
142 For example, some distros need this feature for ALSA-related /dev
143 files for sound to work properly. In short, if you're not sure,
146 To learn more about Access Control Lists, visit the POSIX ACLs for
147 Linux website <http://acl.bestbits.at/>.
150 bool "Tmpfs extended attributes"
154 Extended attributes are name:value pairs associated with inodes by
155 the kernel or by users (see the attr(5) manual page, or visit
156 <http://acl.bestbits.at/> for details).
158 Currently this enables support for the trusted.* and
159 security.* namespaces.
161 You need this for POSIX ACL support on tmpfs.
